21.5" iMac sounds like a Boeing 747 taking off...

Sooo....I have a 21.5" iMac that has been giving me fits for the past couple of months. If I leave it on for more than a day or so, that baby really starts humming and, like the subject line says, sounds like a Boeing 747 taking off. It won't stop unless I shut it down then turn it back on. I ran that istat pro widget and discovered that when operating normally, the hard drives spins at roughly 1700-1900 RPMs. When it starts making that sound, however, it jacks up all the way to 5300-5500 RPMs! Sounds like the hard drive, right? Took to the Apple Store, explained what happened, and they recreated the issues. Sooooo, they changed the hard drive out for me. All was fine until last night when it did it AGAIN! Does anyone have ANY idea what it could be??

Hi, well I would sat it's another trip to the Apple Store, maybe they misdiagnosed! maybe the exchange HD is bad!
Apple warranty their work....L

Sounds like a Boeing 747...

Hi,
I'm testing out a used 1.8 GHz model G5 tower that I'm interested in purchasing. It works great but when the fan kicks in it soulds like my Vornado room fan on high whereas my 2.0 G5 rarely if ever does this.
Does anyone know anything about this issue?
cheers!

Run the hardware tester on it once. Also, try resetting the PMU.

Sounds like 747 taking off after installation, no screen with which to work

Hello,
After I installed Leopard on a dual partitioned hard drive (the other partition has 10.4.9 and FCStudio 1)and Final Cut Studio 2, I then rebooted the computer. It never booted up, but it did sound like a 747 taking off. Only after a few minutes did I have to force a shutdown to end this noise and power. What is going on here and what am I missing? Does it have to do with installing Leopard on a partitioned drive or installing Final Cut Studio 2 on the Leopard side of the partitioned drive? Your help would be appreciated.
Thanks,
Jordan

Never, never never never never never partition any drive where you will be doing/installing, editing etc. any video production.
If you want use Tiger and Leopard, then either install one or the other on a separate, not partitioned drive.
Any do not ever partition any drive where you will be doing/installing, editing etc. any video production.
I guess I said that.
Jordan, video production should be installed and should run a cleanest system possible.
partitioning is not part of that system
in my view

After installation it sounds like a 747 taking off.

I have a dual G5 and that sound you hear always happens when the computer first starts up but quickly stops as soon as an OS is booted, I believe it is all the fans running full tilt. However, in your case, something happened and your system cannot find an OS and therefore that loud roar continues for a long time.
The noise is normal - the fact that it keeps going is not normal but related to a failed install or at least the inability of your system to boot into an OS.
Start it up and hold down the Option key and you should get a screen with all the bootable partitions showing. You should at least see your Tiger OS.
You may have to reinstall or repair the Leopard partition but the Tiger should still be working.

I occasionally get a call and at the end of the call, it sounds like the camera is taking a picture. Anyone else ever experience this

No, but when the other party hangs up first I have heard the click of the disconnect.

Volume up button sounds like the camera is going off

When I press my volume up button it sounds like the camera is going off but no pictures are being taken. Any idea why this happens?
Thanks!

Hello there, JDHMB.
You might want to close out all apps first and foremost:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Then it might be worth attempting a restart of the iPhone, and then a reset, should that not resolve the issue.
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/HT1430
If the sound is still being generated by the phone while using volume controls, you may want to try restoring the iPhone.
iTunes: Restoring iOS software

Thanks for reaching out to Apple Support Communities.

My iMac sounds like a cat purring? Do not remember my Mom's doing that? Any ideas?

My I MAc sounds like a cat purring, is that normal or is this something I should be concerned about. I have only had it forjust over two months? Thanks!

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. Might also apply to new machines the first 90 days. BTW, the AppleCare Protection Plan's the best insurance available for desktop machines. Get it if you don't have it before contacting Apple.

IMac sounds like a fire alarm!

Hi to everyone! I have a problem - i just purchased 27 inch iMac (middle 2010, 3.6 Ghz i5.), and everything was great until i started to edit videos. When i'm trying to start render, it works 1-2 minutes and then computer become sound like a fire alarm, it's sooo loud and terrible, and i have no idea why it happens. I have a 16Gb ram and almost empty 1Tb drive. Does anyone know what's the problem? Thanks

allright, looks like i found a reason of all this messing. probably the problem is in RAM. i removed 2 cards, and now everything works good. photoshop, illustrator, lightroom and premiere are doing export/render at the same time, and i don't see any freezing and alarm. yes, now it's not fast, but i can finish my current projects. try to understand how to upgrade to 16gb again after

IMAC sounds like a fan

When my imac is powered on it sounds like a fan is running. Any suggestions?

When I first bought my 24" iMac (2.4Ghz, white version, not the latest aluminum version), it did exactly the same thing. The fan would be overpowering and sounded like a hairdryer on full blast. As a new Mac user at the time I was pretty surprised!! I even called Apple Support and they told me some special ways to reset the machine (that I don't remember and actually did not work).
To cut a long story short and to hopefully help you out -- I unplugged the power source/cable from the back of the iMac, left it out for about 10 seconds, and then plugged it back in. Rebooted, and everything worked.
I would recommend anyone to try this before anything else. Good luck!

Sleeping G5 Spools Fans until it sounds like a Boeing

Hi all,
I recently received my dad's old work computer as a Christmas gift. It was his main tool for ~3 years, and lived in his office within a woodworking shop (lots of fine dust, lots of serious drafting and rendering usage). Mind you, dad knows his computers, and treated it very well.
Since before it passed into my hands, the computer has begun struggling with fan speed. When running relatively light stuff (youtube vids, loading email, etc.) the fans will speed up and slow down in a seemingly random pattern.
vroooooom
10 seconds of normal fan noise
vrrroooooooooommmmm!!!!
10 minutes of normal fan noise
vrooom
1 minute of normal fan noise
vrrrrroooooooommmmmmmmmmmmmmmm
Although the noise is disconcerting, it doesn't seem to conicide with any decrease in actual computer performance.
The real problem occurs whenever it goes to sleep. At that time the fans spool up, and spool up, and continue to spool up until they are running at what I imagine must be the maximum speed. They will then stay at that speed indefinitely, and can only be stopped by holding the power switch to force the machine off, as it stops responding to normal attempts to wake it up.
I have the option of taking it to a shop, but would like to ask here first. The specs are:
Model Name: Power Mac G5
Model Identifier Power Mac 7,3
Processor Name: PowerPC G5 (3.1)
Processor Speed: 2.7 GHz
Number of CPUs: 2
L2 Cache (per CPU): 512 KB
Memory: 8GB
Bus Speed: 1.35 GHz
Boot ROM Version: 5.2.4f1
Built-In Sound Card: Texas Instruments TAS3004
ATI Radeon 9650 AGP (255MB)
Added USB Slots: pcie55,2928
Pioneer DVD-RW-109 (Revision A912, Protocol ATAPI)
I believe this is a "late 2005", though I'm still a little unclear where the dividing line lies.
Thank you very much!

PowerMac G5 owners hang out over on their own forum, this is Intel Mac Pro that came out post G5
http://discussions.apple.com/category.jspa?categoryID=108
I'd want to look at and for problems with the liquid cooling; dust build up - really open up and take apart some. And look at some of the guides and articles.
Then monitor fans and temps; maybe reset the SMU.
Also, run the CD with Apple Hardware Test.
The trouble with forced shutdown... the disk directory may be left damaged state.

IMac sounds like a vacuum sitting on my desk (it's LOUD)

Hi. I have an iMac G5 (ambient light version) with super drive and the fan runs constantly and very, very loudly. I mean, so loud that even when I turn iTunes halfway up, the fan drowns out the music. I can no longer bear to sit and work at it for very long because of how annoying it is.
It happens even when the computer isn't doing anything in particular. I mainly use Adobe Illustrator but It even runs loud and constant when I'm not using any application other than iTunes.
I have tried resetting the PRAM and restarting holding the 'P' and 'U' buttons (I can't remember exactly what that was called) but I've called apple tech support and they advised me to reset the PMU button. But from my understanding, there isn't a PMU device in this version of the G5. Honestly, they weren't much help. I have added additional memory after i bought it but I didn't have this problem until I took the computer in and had the logic board replaced. Ever since then, it's been super loud and constant.
Any ideas/suggestions would really be appreciated.
iMac G5 Ambient Light Mac OS X (10.4.6)

Usually it would be the logic board. Typical procedure would first be for you to replace the RAM with the original RAM, since third party memory is known to sometimes become incompatible over time. Second would be to suspect corruption in the OS, and reinstall that. Usually they want you to do those things prior to taking it in, to eliminate all non-Apple, non-hardware issues. Good luck.

My iMac sounds terrible! There's like a loud fan or motor running?

Hello,
My iMac sounds like a plane taking off! I will have to confirm what version of OS I am running but does anyone else have this issue? Is it the fan or is it a hardware issue? It has become a little slower over the last couple of months and it's only 8 months old!
Please help!

Problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset:
Resetting the System Management Controller (SMC)
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Sounds like the camera

Whenever I turn the home screen on or off by pressing the on/off switch, I get a sound like the camera is taking a picture.
I have Lookout, which has an option to take the picture of anyone that enters the wrong password x number of times, but I have that disabled.
Does anyone know if this is a "feature" and if I can get rid of the sound? It's getting kind of annoying.

Then i would try Running the phone in Safe Mode and see what it does if the issue stops then you Know there is a 3rd party App that is possibly causing the issue at then you would want to remove each app one by one till the issue goes away). But if the issue remains then i would Look at Running a System Cache, or Doing a Factory Reset.. And as i mentioned in my earlier post holding down the power + lower Volume down will snap a screen shot but continuing to hold will power off the Razr it's referred to as a Power Cycle same thing as you use to do when pulling the Battery.. When i do a power Cycle i hold the button in for at least 30 sec...

New 27'' Imac fan sounds like jet engine

Hi all, i am having some serious issues with my attempt to enjoy apple computers. I am a first time user coming from pc's, just due mainly to the price difference. I just got my first apple computer, a 27'' imac (the standard one, no bells and whistles for this struggling college student). Just want one mainly for recording music and doing research papers. Had to get the first one replaced due to a bad optical drive in the first day. Just brought the replacement home and after 2 days i turn it on and it sounds like a 747 is taking off in my bedroom. I am not the most computer savvy person around, but looked up as much as i could on forums. Tried all the resets and nothing works. Everytime the computer is on there is a turbine that also comes on. I downloaded the istat widget thing and it says my cpu fan is running at over 3000 rpms. I'm no air dispersment specialist, but to me that sounds high. Does anyone know if this is common as of late, and any possible fixes?? I have an telephone appointment with an apple guy tomorrow, but am pretty sure it is going to just turn into a "buy the 3 year $170 applecare plan" speech, like when i called for the disc drive.
Second, are apple computers poorly made?? I know it's wierd asking on the apple website, but i have to get some answers. 2000 dollars is alot of money to me, and the fact that i've had 2 problems in less than a week's time scares me. Should i keep trying to get a good imac that won't crap out, or should i buy something else? Thanks in advance for any replies, i really appreciate it.

Thank you guys for your comments and suggestions. I really appreciate it. I'm thinking of taking it in for repair or replacement. My only concern is that this is 2 times in one week i've had to go and get it replaced. And that's brand new. What is the reliablity for this product going to be in 6 months to a year. For 2000 dollars i don't expect to have to do that. Also apple is not paying my labor to repackage everything, take it down 5 flights of stairs, go to the inconvinently placed apple store at the center of an outdoor mall, pay for my gas, or for my time that i could be using to do something productive. I guess maybe i'm just frustrated, but still. Now if i get a new one i may not be able to enjoy it as much because i will just be waiting for it to break down. Maybe i'll just cut a flap in the new box so i can see the screen and a few holes in the back of the box to run the cables. Then when it breaks down i can just close the flap and push the cables back through, and have it all ready to go back in no time flat. Thank you again for your suggestions, i'm just very ticked off right now.

When using FaceTime, my iMac makes noises. It dings like I am receiving an email and sometimes sounds like a busy signal, but this is while I am talking to someone. Any suggestions?

Dear Mr. Toad (my all-time favorite ride at Disneyland ;-) ..
Thanks so much for your detailed reply.. my netbook is in the bedroom, turned off.. I (so far) only use it in the evening, in the bedroom.. I've saved your response, and will try your suggestions, and let you know if they solve the problem I described. I really appreciate you taking the time to post such a detailed reply..
I can't answer your Thunderbird "configuration" questions, because I'm in the living room, using the crap Vista laptop, on which I plan to install Thunderbird, and then take Windoze Mail out in the street and drive over it a few times.. I'll get back to you one way or the other, and let you know if your instructions solved the problem, or not..
I don't understand why Thunderbird "out of the box", so to speak, simply doesn't forward HTML emails with embedded graphics, (like Outlook Excess, and Winblows Mail do).. without having to go through those steps. I personally HATE HTML email, but over the years, it's become more and more prevelant.. so it's a problem I must fix..
Thanks again..
Harv..
